TLE4923HALA1 Equivalent & Substitute Parts

Part Overview

The TLE4923HALA1 is a digital Hall effect magnetic switch designed for special purpose applications, manufactured by Infineon Technologies. This component operates as a magnetic sensor with temperature compensation, featuring a supply voltage range of 4.5V to 18V and a maximum supply current of 13.6mA. The device is packaged in a 3-SIP SSO-3-06 configuration suitable for through-hole mounting.

The TLE4923HALA1 has reached obsolete product status. Identifying equivalent substitute components is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications utilizing this magnetic switch technology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE4923HALA1 is determined by alignment across the following critical parameters:

Technology & Function: Both the main part and substitute must utilize Hall effect technology for magnetic sensing with digital output capability.

Electrical Compatibility: Supply voltage range must accommodate the original specification (4.5V ~ 18V minimum). Maximum supply current must not exceed system design limits. Output type must be compatible with existing circuit topology.

Mechanical Compatibility: Mounting type must be through-hole. Package configuration must be 3-SIP or equivalent pin-compatible format.

Environmental & Compliance: Moisture sensitivity level, REACH status, and ECCN classification must match or exceed the original specification requirements.

The A1203LUA-T from Allegro MicroSystems meets these substitution criteria as a Hall effect magnetic switch in 3-SIP packaging with compatible electrical and mechanical characteristics.

Engineering Selection Recommendations

The A1203LUA-T is the manufacturer-recommended substitute for the obsolete TLE4923HALA1. Selection of this alternative is supported by the following factors:

Product Status: The A1203LUA-T maintains active product status with established supply chain availability, whereas the TLE4923HALA1 is obsolete. This ensures long-term component sourcing and production continuity.

Compliance Alignment: Both components share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and moisture sensitivity level (MSL 1 - Unlimited), ensuring regulatory and environmental compliance requirements are maintained.

Electrical Compatibility: The A1203LUA-T supply voltage range (3.8V ~ 24V) encompasses the original specification (4.5V ~ 18V). Supply current consumption of the substitute (7.5mA maximum) is lower than the original (13.6mA maximum), providing improved power efficiency. Output current capability (25mA) supports standard digital logic interfacing.

Mechanical Compatibility: Both components utilize through-hole mounting in 3-SIP package configurations, enabling direct physical replacement without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the A1203LUA-T directly replace the TLE4923HALA1 without circuit modifications?

A: The A1203LUA-T is pin-compatible in 3-SIP through-hole packaging and operates within the voltage range of the original design. However, the output type differs (open drain versus digital). Circuit topology must be evaluated to confirm compatibility with the open drain output configuration. Pull-up resistor requirements may differ between the original and substitute designs.

Q: What are the key differences in electrical performance between these components?

A: The A1203LUA-T operates at a lower maximum supply current (7.5mA versus 13.6mA) and provides specified output current capability (25mA). The substitute supports an extended supply voltage range (3.8V ~ 24V versus 4.5V ~ 18V), offering greater design flexibility. The A1203LUA-T includes latch function capability with defined sensing thresholds (9.5mT trip, -9.5mT release) and operating temperature range (-40°C ~ 150°C).

Q: Are there any package or mounting considerations for substitution?

A: Both components use through-hole mounting in 3-SIP packaging. The TLE4923HALA1 is specified as SSO-3-06, while the A1203LUA-T is specified as 3-SSIP. These designations refer to equivalent 3-pin single in-line package formats suitable for through-hole PCB assembly. Pin spacing and footprint compatibility should be verified against your specific PCB design.

Q: What compliance certifications apply to the A1203LUA-T?

A: The A1203LUA-T maintains REACH Unaffected status, identical to the original component. It carries EAR99 ECCN classification and MSL 1 (Unlimited) moisture sensitivity rating. The component is RoHS3 compliant, exceeding the compliance profile of the obsolete TLE4923HALA1.

Q: Is the A1203LUA-T the only available substitute for the TLE4923HALA1?

A: The A1203LUA-T is the manufacturer-recommended substitute provided in the official substitution documentation. This component meets all critical substitution criteria based on technology, electrical parameters, mechanical compatibility, and compliance requirements.
